Various materials and designs are prepared as long as they are angles generally used in construction such as 0 degrees and 120 degrees. However, in a place such as a staircase, a general inclination angle cannot be adopted due to architectural design restrictions, and a halfway angle must be adopted in many cases. In such a case, the connection of the bent part of the handrail is forced to employ a hand-made joint, which is very expensive.
